ebm-papst EC Technology – five examples for efficiency

The equation is as simple as can be: Wherever energy is saved, money is saved, too. Just see for yourselves. Five examples taken from typical applications represent the enormous saving potential in terms of energy, CO2 and costs made possible by GreenTech EC technology.

29%

6 GreenTech EC fans work in one heat exchanger. At an average duty cycle of 75 % this means an annual savings potential of over 24 MWh. This corresponds to approx. 14.4 tonnes of CO2 and saves 2,814 euro*.

e. g. A3G800 Axial fan

67%

A small supermarket operates 40 fans in the refrigeration counters. The lower intrinsic heating of the energy-saving motor allows a 30 % shorter working time. Over a year, that means a savings potential of more than9.4 MWh and 5.6 tonnes of CO2. Cost saving: 1,080 euro*.

e. g. W1G200 Axial fan

79%

In a medium-sized factory are 50 control boxes with air filters running in continuous operation. Exchanging the conventional AC fans could save6.5 MWh of energy over a year. The fans will have paid back the extra cost after just 4–6 months.

e. g. ACi 4400Axial compact fan

22%

6 precision air conditioning units are working in the IT rooms of a computer centre, each equipped with 3 GreenTech EC fans. With a duty cycle of 100 %, up to 50 MWh of electricity can be saved. That corresponds to about 30 tonnes of CO2 and 5,898 euro* every year.

e. g. R3G500 Centrifugal fan

30%

8 centralised air conditioning units are operating in a shopping centre. With a duty cycle of 100 % and ventilator operation according to actual requirements, the annual savings potential is 291 MWh and 34,081 euro. CO2 emissions are reduced by about 175 tonnes.
